In units that consist of a condensing steam turbine coupled with an propylene compressor, what causes fluctuations in speed, flow rate, and the speed control valve?

This can be analyzed from two aspects: one is the fluctuation in the load of the propylene unit, which causes fluctuations in the speed of the turbine, and the other is the fluctuations in the turbine itself. I would like to ask Haiyou: have you carefully checked whether the load on the propylene unit fluctuates during fluctuations?

Check the pressure in the steam piping network as well as the vacuum level of the exhaust gas

Is it caused by a stuck speed control valve? Further careful observation is needed
